This type of fasteners is used for the installation of various structures for all types of concrete products, not only full-bodied, but also cellular. Structurally, the anchor bolts consist of two main parts - a spacer and a stud. The technology of production is the same, the difference is only in linear parameters, form and additional "adaptations."
All products have their own numerical designations( in "mm").For example, 8/10 x 50. How are the numbers deciphered?
- The first is the thread size( 8).
- The second is the diameter( 10).
- The third is the length of the product( 50).
What size are anchors for concrete?
- Thread - from M5 to M20.
- Diameter - from 6 to 24.
- Length - from 18 to 400.
Choosing the right product size is not all. It is necessary to think about the convenience of production of installation works, the features of the operation of those items( devices) that are fixed. Therefore, in order to have a more complete picture of anchor bolts, it is worth pointing to the main varieties of this type of fasteners( for dowels, read here).
With washer
Such products are used if you need to press something tightly against the mounting surface. For example, the housing of a household appliance, a piece of furniture "hinged" type.
With nut on the end
With it it is convenient to place at a height of massive objects. Corresponding holes in the body are "put on" on the bolts previously installed in the wall, and then fixation in place of the nut is made.
"L-shaped" form
With the help of such products it is convenient to attach heavy household appliances, which will have to be periodically removed from the installation site. For example, wall boilers, boilers and the like( for repair or maintenance).
With ring, hook
As a rule, they are used for installation of lighting devices, for installation of utility lines and in a number of other cases.
The selection of the appropriate bolt size is made individually for each fastened product. The rule is simple - the more massive the object, the thicker the fastener should be. As for the length, it is also necessary to be guided by the thickness of the base on which the installation is made.
In principle, this information is enough to make the best choice. But in particularly problematic cases, you should review the data on the maximum load in the attached table, in which, in addition, the correction factors for the dimensions and recommended distance are specified.
